What need to mainly focus on is fixing the lag is the one probally causing all these other issues. (It started happen after 10.3.183.5) Perfromance Slowdown countines. Even try cleaning it its fast in the beginning than it gets laggy so it must be memory leak they never notice.

The feature request is now available at the following address:

https://bugbase.adobe.com/index.cfm?event=bug&id=2960407

Adobe closed the above "feature request" saying that it is "not a bug"... To lighten up the treasure hunt, the html page now includes a link to download the latest version. The control panels remain a mess, both the installed one and the remote one, the updates will continue to be applied by hand, the swf plugin in Acrobat will continue to be out of sync and both open to security attacks...

In July we spotted a Mac OS 10 with Acrobat 8 that did not want to upgrade. The Acrobat page did not want to list version 10, so we had to force the right update by hand, via the usual treasure hunt to bypass the faulty automatic selection.

Another problem, related to flash, is that the Acrobat plugin stopped working with the introduction of Safari 5.1 on Mac OS 10.7.1.

None of the above problems is in the agenda for Flash 11, and its pre-release does not introduce solutions.

I've been having the same issues since July.  A friend of mine pointed me to this thread and mentioned others were having the same issues as me.  At the time I was running Windows XP 32 bit and the most current version of flash at that time, using firefox as my web browser.  I encountered the same symptoms on both my desktop and my laptop pc, which was and is running Windows 7 and using firefox.  I experienced similar problems at the time using IE.  Prior to these problems I used to watch videos frequently on sites such as MegaVideo, Novamovies, Megashares, etc.  The only way I can describe the symptoms is as another member did... lag.  If I watch a video as its loading it seems to work fine, but if I pause the video, it seems like the longer the video is open the slower the playback is.  The audio is fine, but the video lags, skipping a large number of frames at a time and "jumping" ahead.  I used to be able to pause a video, let it buffer and then come back and watch it days later, but now I can't even go 24 hours.

Since then, I have upgraded to Win 7 on my desktop, I have upgraded my video card as well and no longer rely on my onboard video.  I have upgraded to Flash 11, and Firefox 7, and I still have seen these same problems with every update that comes out.  The fact that I'm experiencing the same issue with two different pc's tells me that something was changed and not fixed, but I'm surprised this has gone on for so long and not been repaired through many updates to adobe and firefox.   I do not know if the problem still occurs in IE.  I can check it out.  I don't use IE ever.
